testing the ignition coil

so i have my 5.0L in my ranger and i can crank it over and have fuel pressure. but i'm not getting spark. i've followed this worksheet to diagnose the no spark: http://www.therangerstation.com/tech..._worksheet.jpg
but everything checks out good. my question is when testing the ignition coil it says to put a test light on the negative side (which i get 12v on) and crank it over and it should pulse the light. it does that for me but its a weak pulse and with the multimeter it shows it dropping from 12v down to 8v-9v and fluctuating around there. so i'm guessing thats good. but it does the same thing when i put the test light on the positive side. should the positive on the ignition coil be a constant 12v or should it fluctuate during cranking like the neg side?
